In 2010 I had a small bowel resection as a result of carcinoid tumors in my small intestine. My ileocecal valve was also removed. The diarrhea became manageable after my cardiologist brother suggested cholestyramine for the burning. The follow up GI doctor was of no help. About two years ago I was hospitalized with sepsis fro a rare bacterial infection. The 8 week course of IV antibiotics (Zosyn) played havoc with my gut and, as a result I was hospitalized again with a critical deficiency of potassium, magnesium etc. I was never given any kind of diet so keeping the diarrhea at bay has bit hit or miss. I know very little about SIBO but I've read conflicting information on whether it is common in folks without the ileocecal valve. I've also read that people have had success with L-glutamine. I have an appointment with a new GI Doc in a month, so hopefully this one will have more knowledge of my condition.
